POP3 (Post Office Protocol Version 3) is a standard e-mail retrieval protocol. It works by downloading emails from a server to a single computer and then deleting them from the server. The downloaded emails will then only be accessible from that device. If you wish to access the emails from another device, the previously downloaded emails will not be available.
